offer 2 options for your 6.6L Duramax LMM EGR delete. The EGR delete kit with a high-flow intake elbow boosts airflow and performance for tuned engines, while the standard kit focuses only on EGR removal for cost-conscious users maintaining stock setups.
Key Function Difference
EGR Delete Kit WITH High Flow Intake Elbow Pipe
- Improved Airflow: Reduces intake restriction, increases air volume, and enhances turbo response for smoother power delivery.
- Lower Intake Temps: Optimized elbow design helps reduce air intake temperatures, improving combustion efficiency.
- Performance-Oriented: Ideal for tuned engines, larger turbos, or other upgrades to maximize power potential.
EGR Delete Kit WITHOUT High Flow Intake Elbow Pipe
- EGR Removal Only: Solves carbon buildup and overheating issues but retains the stock intake system.
- Budget-Friendly: Lower cost, suitable for users not seeking extra airflow upgrades.
- Daily Driving Focus: Meets basic power and fuel economy needs but offers limited airflow improvement.
Best For
- High-flow version: Performance builds, towing, or tuned trucks needing better airflow.
- Standard version: Daily drivers prioritizing reliability and basic EGR-related fixes.
Installation
What Are The Benefits of EGR Delete?
An EGR delete can bring about several benefits. These include:
Improved Fuel Economy and Engine Longevity
An EGR delete helps you restore your diesel engine’s power levels which, in turn, also restores your overall fuel efficiency. Since an Duramax EGR delete kit sends the exhaust gas away from your car’s engine, it starts to run cleaner, too. Not only does it make the process increasingly efficient, but it also reduces the chances of DPF (diesel particulate filter) failure. So, overall, with this aftermarket kit, you can see an increase of up to 20% in your fuel economy. Along with that, the EGR delete kit can also improve your engine’s longevity.
Reduced Engine Temperature
EGR valves naturally contain a high content of soot. When the EGR system’s valve or coolers get clogged with soot, the exhaust gases start to circulate more around the system, resulting in a blockage. As a result, the temperatures around the engine rise and you experience a reduction in the engine’s power. However, when you bypass this, lower exhaust gas is produced. In turn, during operation, your vehicle experiences a reduced engine coolant temperature.
Helps Save Money
In addition, an EGR delete can also help you save money on some costly repairs. The EGR, if damaged, can be quite costly to repair and replace. An EGR delete removes the possibility of such damage, thereby saving your money.

Frequently Asked Questions
What is a delete tuner?
A delete tuner is a device that reprograms yourtruck's ECM (computer) to turn off emissionssystems like the DPF, EGR, and DEF, allowing yourtruck to run without those components
Can l use a delete tuner withoutphysically removing TheDPF/DEF/EGR parts?
You MUST remove your DPF(Diesel ParticulateFilter), as the filter will clog and stop all exhaust flowwhen shut off. You will no longer need DEF(DieselExhaust Fluid), and you may remove your DEF tankif you wish, or it can sit empty. The EGR may remainas is, but we recommend removing the physicalparts as well.
Is a Delete Tune bad for mytruck's engine?
Quite the opposite. In fact, many customers reportimproved engine life, smoother shifting, and betterfuel economy (typically 3-5 MPG gains) when usinga quality delete tuner.
What's the difference between adelete tuner and a delete tune?
The tuner is the hardware device. The tune is thesoftware file that gets uploaded to your truck's ECM.Your delete tuner includes a delete tune when youpurchase from us.
Do delete tuners void my warranty?
Yes. Any emissions-related modification, includingtuning, can void the manufacturer's warranty. Manycustomers wait until after their warranty expiresbefore deleting.
Do l need a mechanic to install thetuner? How long does installationtake?
Not necessarily. Many of our customers install their delete tuner themselves in under 30 minutes. We include easy-to-follow instructions, and our support team is available if you need help.
Will my truck pass inspection oremissions testing with a deletetuner?
No. Delete tuners disable emissions systems, so your truck will not pass emissions tests in areas where they're required. Some states have exemptions (e.g. heavy-duty or rural-use trucks).
Can l go back to stock afterinstalling a delete tuner?
Yes. However, in most cases you will have to have the ECM flashed at the dealership. If this is a concern, contact our team and we can explain further.
Is the delete tune VlN-locked?
Yes. All delete tunes are VIN specific and will only work on one truck. The tuner (hardware device), may be used on multiple vehicles for diagnostic or monitoring purposes where applicable.
What support do l get with my tuner?
We offer lifetime customer support, step-by-step install guides, and remote help from our tuning team. You're never left hanging, even after the sale.
